Ignorance isn't an excuse for bad design. The fact that you know about them and don't want to learn how to use them in a systems makes this a travesty. (With apologies for the blunt honest truth; i've had a long weekend)

I currently have this stored procedure:
<br />
@id as bigint,<br />
<br />
AS<br />
SELECT Meetings.meetinguser, Companies.name, Meetings.meetingdate <br />
FROM Companies INNER JOIN Meetings <br />
ON (Companies.id = Meetings.company) <br />
WHERE (Meetings.complete = 0)<br />
FOR XML AUTO, ELEMENTS<br />
Meetings.meetinguser is an ID number that also appears in the User table.
User.UserName is the name that coresponds to that ID.
At the moment this returns:
UserID CompanyName Date
I would liek it to return:
UserName CompanyName Date.
I was not sure about using more than one join in a single query...
Can any one, please, help ?
Thanks

SELECT User.UserName, Companies.name, Meetings.meetingdate
FROM Companies, Meetings, User
WHERE Companies.id = Meetings.company AND User.id = Meetings.meetinguser
AND Meetings.complete = 0
ought to do it.

Simply add
INNER JOIN User
ON MeetingsUser.UserID = User.UserID after the existing ON clause and before the WHERE clause. You can have as many join clauses as you need.
Stability. What an interesting concept. -- Chris Maunder

Read up on the DateAdd function.

String or binary data would be truncated.

)

Or your select statement is out of order with the column names. Depending on the difference you will have to case fields in the select statement to match the column definitions in the result table.

Hi,
This problem occurs when you trying to insert to field a string that exceeds fields length. The only solution I could find was to set a bigger field length.
Check the length of the datatype of table in which you are inserting...
May be the length of the data type from the table whose contents you are inserting is greater than that of the table in which insertion is made.
Try out...
Good Luck!

Is there a way to have the progress bar increment for each record that will be imported?
When I d0 a select * (or whatever), does it bring the records in one-by-one where a progress bar can be set up?
Thanks,

No, I would use some type of animated gif (similar to the one that windows uses when empting the “recycle bin”) display it while your importing upon completion hide it.

I was hoping for something a little more accurate. Anyone have any ideas?

I have no idea what language you’re using; MySQL is a database server not a programming language. What was so inaccurate about my suggestion? 
Rabbit17 wrote: Anyone have any ideas?
Sure I have lots of ideas, a few even pertaining to the topic at hand. 
When selecting information from a database, you don’t know how many rows will be returned, which for all practical purposes you will have no idea how long it’s going to take that operation to complete.
I have used things like the gears turning, progress bar (that bounces back and forth quickly) to the jack in box they all work on the same principal. Start playing your animation before beginning the complex operation and hide it when finished.
If you peruse through this site there are is a whole host of different animations to choose from.

I keep getting an exception when I call the DataAdapter Update method.
I have been trying to figure out what is causing the null reference
exception for this code for what seems like forever:
private void DoInserts(OdbcDataAdapter odbcDataAdapter, string
tableName)
{
DataTable dataTableChanged =
dsTapes.Tables[tableName].GetChanges(DataRowState.Added);
if ((dataTableChanged != null) &&
(dataTableChanged.Rows.Count > 0))
{
// Open the connection if its not already open.
if (odbcConnection.State !=
System.Data.ConnectionState.Open)
{
odbcConnection.Open();
}
//Create a new transaction.
odbcDataAdapter.InsertCommand.Transaction =
odbcConnection.BeginTransaction();
try
{
//Submit the changes.
odbcDataAdapter.Update(dsTapes,
dataTableChanged.TableName.ToString());
//Commit the changes and close the connection.
odbcDataAdapter.InsertCommand.Transaction.Commit();
}
catch (Exception ex)
{
odbcDataAdapter.InsertCommand.Transaction.Rollback();
throw (ex);
}
}
}
The exception information has not been helpful. All it says is: "Object
reference not set to an instance of an object."
I don't know if this will help, but the Insert command looks like this:
tapeLogInsert = odbcConnection.CreateCommand();
tapeLogInsert.CommandText =
"INSERT INTO " + tapeLogODBCName.Trim()
+ " (NBR, Backup_Name, BakDate, ScrDate, Location, "
+ "Tape_No, Tape_Set, Usage, Comment, UseDate) "
+ "VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
tapeLogInsert.Parameters.Add(new OdbcParameter("NBR",
OdbcType.Int));
tapeLogInsert.Parameters["NBR"].SourceColumn = "nbr";
tapeLogInsert.Parameters.Add("Backup_Name", OdbcType.Char, 17,
"backup_name");
tapeLogInsert.Parameters.Add(new OdbcParameter("BakDate",
OdbcType.DateTime));
tapeLogInsert.Parameters["BakDate"].SourceColumn = "bakdate";
tapeLogInsert.Parameters.Add(new OdbcParameter("ScrDate",
OdbcType.DateTime));
tapeLogInsert.Parameters["ScrDate"].SourceColumn = "scrdate";
tapeLogInsert.Parameters.Add("Location", OdbcType.Char, 1,
"location");
tapeLogInsert.Parameters.Add(new OdbcParameter("Tape_No",
OdbcType.SmallInt));
tapeLogInsert.Parameters["Tape_No"].SourceColumn = "tape_no";
tapeLogInsert.Parameters.Add(new OdbcParameter("Tape_Set",
OdbcType.SmallInt));
tapeLogInsert.Parameters["Tape_Set"].SourceColumn = "tape_set";
tapeLogInsert.Parameters.Add(new OdbcParameter("Usage",
OdbcType.SmallInt));
tapeLogInsert.Parameters["Usage"].SourceColumn = "usage";
tapeLogInsert.Parameters.Add("Comment", OdbcType.VarChar, 50,
"comment");
tapeLogInsert.Parameters.Add(new OdbcParameter("UseDate",
OdbcType.DateTime));
tapeLogInsert.Parameters["UseDate"].SourceColumn = "usedate";
tapeLogAdapter.InsertCommand = tapeLogInsert;
Does any one have any idea what is going on here or how to go about
finding out? Any suggestions would be appreciated: I don't even know
how to figure out which reference is null!

When using c#, I've found I have to re-reference the commands when using CreateCommand.
Try:
odbcCommand tapeLogInsert = odbcConnection.CreateCommand();
instead of:
tapeLogInsert = odbcConnection.CreateCommand();
even if you lead with:
odbcCommand tapeLogInsert = new odbcCommand();
tapeLogInsert = odbcConnection.CreateCommand();
Hope that helps

I am tring to create a table in a mdb file, but the maximum number of columns i can add is 40. When i try to add the same number (or move) of columns from the access interface, there is no problem.
Can you tell me if it is something i overlooked.
The connection string to the mdb file is : Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<filepath>
I am using C#, on .NET Framework 1.1 and the connection class is OleDbConnection

So, what is the error you get? What is the SQL you are using?
|
|
|
|

I'm using the next sequence of SQL:
CREATE TABLE Table_1 ( ID char(50) PRIMARY KEY);
After the creation of the table i'm using a for cycle to add as many columns in the table as necesary. (max. 200)
The query run in the for cycle is: ALTER TABLE Table_1 ADD column_i char(50); - where "i" is the counter
I get the following error when i add more then 40 columns:
System.Data.OleDb.OleDbException: Record is too large.
at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(Int32 hr)
at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams, Object& executeResult)

You are exceeding a published limit for Microsoft Access:
Access XP allows a maximum of 2000 characters per record in a Table.
Access 2003 allows 4000, but depending on your connection string,
you may be using the access xp engine version even thought the application version
you have is 2003, which would explain why you can interactively create
up to 80 fields of Char(50) data. See this[^] for a list of the limitations.
BTW, a table with 200 50 char fields does not look like a very good design...

I know is not very good, but it was only a test. The type of the fields will be changed when i start codding seriously.
10x for the link.
